Expert Audio, Video, Telecom DSP / Embedded Software Engineer

Software engineer with deep expertise in the Audio/Video Digital Signal Processing (DSP) and Embedded Systems technology areas. I have 15+ years of experience in these highly specialised fields, working for global industry leaders (NXP Semiconductors, Cisco, Tandberg, Infineon, Creative Labs). My work has been widely used in numerous consumer electronics applications/devices and has also resulted in several patent grants for related technology innovations. I specialise in providing my clients with smart and robust technical solutions that are custom engineered for their requirements. My expertise covers the full product life cycle, comprising: - Product concept analysis. - DSP algorithms research. - Hardware prototyping. - Software porting to fixed point. - Software integration on DSPs / microcontrollers. - Real time algorithm optimisations. - Automated verification and test harness development. - Firmware release and updates management.

MIDI Violin implemented on Starter Kit with DSP TMS320C31

Acta Tehnica Napocensis, vol. 40, nr. 1, 2000, ISSN1221-6542
Description of a MIDI Violin: • 4 channel DSP real time audio acquisition & processing system which estimates the violin pitch and transmits it as MIDI signals in real time. • The frequency estimation is done using the Chirp Z Transform algorithm, which provides 1/10 semitone frequency resolution, close to the human ear perception. • Board with TMS320VC33 which contains a 4 channel ADC, 2x24 LCD and a Push Buttons matrix controller, working as a real time embedded system.
